How to disable or override clipboard support
Diagram provides support to enable, disable, and handle the clipboard commands. Clipboard commands allow you to cut or copy the selected objects in the page to the clipboard and paste the valid clipboard content into the page. The Cut, Copy, and Paste command are KeyGesture commands.
Disable Cut, Copy, and Paste command:
DiagramView provides properties to enable or disable the Cut, Copy, and Paste commands.
Refer to the properties as follows.
IsCutEnabled | Defines a value whether cut operation for the diagram is enabled or not. The default value is true. |
IsCopyEnabled | Defines a value whether copy operation for the diagram is enabled or not. The default value is true. |
IsPasteEnabled | Defines a value whether paste operation for the diagram is enabled or not. The default value is true. |
Refer to the code example as follows.
<!--Diagram Control--> <syncfusion:DiagramControl Name="diagramControl"> <syncfusion:DiagramControl.Model> <syncfusion:DiagramModel x:Name="diagramModel"> </syncfusion:DiagramModel> </syncfusion:DiagramControl.Model> <!-- Disable Cut, Copy, and Paste --> <syncfusion:DiagramControl.View> <syncfusion:DiagramView IsCutEnabled="False" IsCopyEnabled="False" IsPasteEnabled="False" Name="diagramView"> </syncfusion:DiagramView> </syncfusion:DiagramControl.View> </syncfusion:DiagramControl>
Note: The “IsCopyEnabled, IsPasteEnabled, and IsCutEnabled” properties can be used, when your custom implementation does not depend on Ctrl + C and Ctrl + V key combinations.
Override the clipboard commands (disable default clipboard action)
The KeyGesture commands are overridden by the ApplicationCommands (Cut, Copy, and Paste), and those commands are not triggered.
Remove these Cut, Copy, Paste from DiagramView as shown in following code example.
Refer to the code example as follows.
for (int i = 0; i < diagramView.CommandBindings.Count; i++){ CommandBinding cb = diagramView.CommandBindings[i]; if (cb.Command == ApplicationCommands.Copy || cb.Command == ApplicationCommands.Cut || cb.Command == ApplicationCommands.Paste) { diagramView.CommandBindings.Remove(cb); i--; }} Here, diagramView is an instance of DiagramView.
